Spatial distribution of the most abundant sea urchin populations on the southeast coast of Sao Paulo (Brazil)
The spatial variability of Echinometra lucunter, Lytechinus variegatus and Arbacia lixula was studied in relation to four spatial scales (105, 104, 103 and 102 m) and two depths (0–3 and 3–8 m), along 100 km of the São Paulo coastline (August to October 1996). Echinometra lucunter was the...

Echinometra lucunter fue la especie más abundante, prefiriendo los fondos más someros bajo el efecto del oleaje. Se identificó un gradiente en su abundancia, aumentando en dirección del suroeste al noreste. Arbacia lixula mostró el mismo gradiente, pero con una mayor abundancia en el sector más profundo. Ambas especies mostraron diferencias significativas a una escala espacial de centenares de metros y E. lucunter también a una escala de kilómetros. Lytechinus variegatus mostró un patrón en mosaico, siendo abundante en ciertos sitios. Las variaciones en la calidad del agua y en la heterogeneidad natural del hábitat podrían explicar de forma conjunta la distribución espacial de estas poblaciones.Iniversidad Autónoma de Baja California2001-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/37110.7773/cm.v27i1.371Ciencias Marinas; Vol. 27 No. 1 (2001); 139-153Ciencias Marinas; Vol. 27 Núm. 1 (2001); 139-1532395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/371/319info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/3712024-08-22T17:01:30Z |
